Installation

Configuration

Create your Facebook App. NOTE: You cannot use a Facebook Page to create a Facebook App. You must use your personal Facebook profile. However, once you create your Facebook App, you can use its App ID and App Secret along with the Facebook ID of the Facebook Page you want to get the feed from on the settings page for the plugin.

If you get a Request for Permission prompt, then Allow Developer to access your basic information.

Click Create New App.

Enter an App Name. I suggest using the name of your blog. All the other entries are optional. Click Continue. You will be prompted with a security check.

On your App page, enter your App Domain. Set Sandbox Mode to Disabled. Under Select how your app integrates with Facebook click Website with Facebook Login and enter your Site URL. Do not use www. in your App Domain or Site URL. Save your changes.

Record your App ID and App Secret. You will need these later.

Go to JSL3 Facebook Wall Feed under Settings on the Dashboard menu.

Enter your Facebook ID. If you do not know your Facebook ID, then use the Graph API Explorer. Click Get Access Token. You may be prompted to log in. If you are prompted to Select permissions, click Get Access Token. In the text box next to the Submit button, enter the Facebook Username used in your Facebook URL (for example, my Facebook URL is http://www.facebook.com/takanudo so my Facebook Username is takanudo) followed by ?fields=id. Click Submit. Your Facebook ID will be in the results.
Enter the App ID and App Secret you recorded earlier. Click Save Changes.

You will be redirected to Facebook. You may be prompted to Log In a couple of times.

Widget Usage

Go to Widgets under Appearance on the Dashboard menu.

Drag the JSL3 Facebook Wall Feed widget to the sidebar of your choice.

Give the widget a title (or leave it blank) and enter how many posts you want to get from your wall. You may also enter the Facebook ID of the Facebook page you want to display in the widget. If you leave the Facebook ID blank, the widget will use the Facebook ID entered on the settings page for the plugin. Click Save.

Shortcode Usage

Add the shortcode [jsl3_fwf] or [jsl3_fwf limit="1"] or even [jsl3_fwf limit="1" fb_id="1405307559"] to the Text view of a post or page. If you do not enter a Facebook ID, the plugin will use the Facebook ID entered on the settings page for the plugin.

How do I use shortcode to add the Facebook Wall Feed to a post or page?

Switch to HTML view and add the following:

[jsl3_fwf]

To limit the number of posts displayed add the ‘limit’ attribute:

[jsl3_fwf limit="1"]

To specify a specific feed to display add the ‘fb_id’ attribute and enter the feed’s Facebook ID:

[jsl3_fwf limit="1" fb_id="1405307559"]

If you do not enter a Facebook ID in the shortcode, the plugin will use the Facebook ID entered on the settings page for the plugin.Back to the FAQ menu

Can I translate the plugin?

I would be happy if you translated the plugin. You can use the ‘default.po’ file found in the ‘wp-content/plugins/jsl3-facebook-wall-feed/languages’ directory. Use Poedit to translate the plugin into your language and then save the PO file using the text domain (‘jsl3-fwf’), language code and country code as the name. For example, if you translate the plugin into German, you should save the file as ‘jsl3-fwf-de_DE.po’. Finally, place the translated PO file and its corresponding MO file in the ‘wp-content/plugins/jsl3-facebook-wall-feed/languages’ directory.

To remove the ‘Facebook Status’ box add the following to the bottom of the style sheet on the settings page for the plugin:
/* Remove Facebook Status */
#facebook_status_box h2
{
display: none;
}Back to the FAQ menu

How can I adjust the width of the Facebook Wall Feed?

To adjust the width of the Facebook Wall Feed add the following to the bottom of the style sheet on the settings page for the plugin:
/* Adjust width */
#facebook_status_box
{
width: 225px;
}
Change the number in front of “px” to one that fits for you.Back to the FAQ menu

How do I adjust the height of the Facebook Wall Feed?

To adjust the height of the Facebook Wall Feed add the following to the bottom of the style sheet on the settings page for the plugin:
/* Adjust height */
#facebook_status_box
{
height: 500px;
}

#facebook_status_box #facebook_canvas
{
height: 460px;
}
Change the numbers in front of “px” to ones that fits for you. Try to keep the height in #facebook_status_box about 40px greater than the height in #facebook_canvas if you are keeping the ‘Facebook Status’ box at the top of the feed.Back to the FAQ menu

Why is there so much space at the bottom of my page where the plugin is located?

To add the like icon to comments, add the following to the bottom of the style sheet on the settings page for the plugin:
#facebook_status_box .fb_post .fb_comments .fb_comment_likes
{
background-image: url("https://fbstatic-a.akamaihd.net/rsrc.php/v2/y-/r/tbhIfdAHjXE.png");
background-repeat: no-repeat;
background-position: 0 -60px;
height: 14px;
padding-left: 18px;
margin-left: 5px;

Why is my token set to expire in less than 24 hours?

I am not sure why Facebook will give some users a short-lived token. Facebook will only allow you to attempt to renew your token once per 24 hours. Try waiting 24 hours from the last time you clicked “Save Changes” on the settings page for the plugin, then try again. If you do not get a token that lasts about 60 days, then you may want to try creating a new Facebook App for the plugin.Back to the FAQ menu

What does the error “OAuthException: Error validating access token: Session has expired at unix time [UNIX TIME]. The current unix time is [UNIX TIME]” mean?

It means your access token has expired. Go to the settings page for the plugin and click “Save Changes” to renew your token.Back to the FAQ menu

What does the error “OAuthException: Error validating access token: The session has been invalidated because the user has changed the password” mean?

It usually means you changed your Facebook password recently. Go to the settings page for the plugin and click “Save Changes” to validate your session.Back to the FAQ menu

What does the error “OAuthException: An access token is required to request this resource” mean?

It usually means you do not have an access token. Check that your App ID and App Secret are correct. Then click “Save Changes” on the settings page for the plugin.Back to the FAQ menu

What does the error “Exception: No node specified” mean?

It usually means you have not set your Facebook ID. Check that you have entered your Facebook ID on the settings page for the plugin. Then click “Save Changes” on the settings page for the plugin.Back to the FAQ menu

What does the error “Exception: SETTINGS: Unrecognized pref_type 0 for NullProfileSettings pref name default_non_connection_tab” mean?

It usually means are using an incorrect Facebook ID. Check that your Facebook ID is correct. Then click “Save Changes” on the settings page for the plugin.Back to the FAQ menu

API Error Code: 191
API Error Description: The specified URL is not owned by the application
Error Message: Invalid redirect_uri: Given URL is not allowed by the Application configuration.

This error means that the App Domain and Site URL for your Facebook App do not match the domain of the website where you are using the plugin. Go to https://developers.facebook.com/apps and click “Edit Settings”. Under “Basic”, change your “App Domain” to match the domain of the website where the plugin is located. In the “Select how your app integrates with Facebook” section, under “Website with Facebook Login”, change your “Site URL” to match the URL of the website where the plugin is located. Do not use “www.” in your App Domain or Site URL.Back to the FAQ menu

Why is my feed blank?

First, a blank feed usually indicates an invalid Facebook ID. If you do not know your Facebook ID, then go to https://developers.facebook.com/tools/explorer. Click “Get Access Token”. You may be prompted to log in. If you are prompted to “Select permissions”, click “Get Access Token”. In the text box next to the “Submit” button, enter the “Facebook Username” used in your Facebook URL (for example, my Facebook URL is https://www.facebook.com/takanudo so my Facebook Username is takanudo) followed by “?fields=id”. Click Submit. Your Facebook ID will be in the results.

Second, The limit property tells Facebook how many posts to return. Some of those posts could be filtered out depending on how you have configured the plugin. For example, if you set the limit to one, the post returned may be filtered out if you have “Only show posts made by this Facebook ID” checked or “Show all status messages” unchecked or “Privacy” set to “Show only wall posts labeled public”. The thoroughness option forces the plugin to keep making requests to Facebook until the limit number has been reached, but it will slow down the plugin dramatically.Back to the FAQ menu

1.0

Upgrade Notice

1.7.2

Fixed a timing bug where the access token renew check would be scheduled to run before the expiration date was stored in the database.

1.7.1

A minor update to add group permissions to the feed.

1.7

The plugin now has the abiliy to display feeds from different Facebook pages. Also, a German translation of the plugin has been provided.

1.6

Facebook removed the likes count from the feed. This update uses a different method to get the likes count for each post. The plugin also displays the likes count for each comment.

1.5.5

The help section has been updated.

1.5.4

Hopefully this update will send fewer email notifications when your token is about to expire. Also, changed all URLs to use https.

1.5.3

Fixed a minor bug introduced in v1.5.2.

1.5.2

Facebook changed public privacy setting to be a blank entry, so I have adjusted the plugin to account for that. Also, for some users, the style sheet would be embedded more than once. This update should fix that.

1.5.1

This is a minor shortcode bug fix.

1.5

This update adds an option to disable the make_clickable() WordPress function added in v1.4.2. Also, the automatic Facebook access token renewal added in v1.4.1 never worked properly. So now the plugin will now notify the WordPress admin that their Facebook access token is about to expire a week from the expiration date. Renewing the token should simply be a matter of clicking “Save Changes” on the settings page for the plugin.

1.4.2

This is a minor update that adds the make_clickable() WordPress function to convert plain text URI to HTML links.

1.4.1

This update adds additional security features. It also adds a CRON schedule to refresh expired tokens because Facebook no longer allows non-expiring tokens.

1.3.1

This update should validate under XHTML 1.0 Strict. It also checks to see if cURL is loaded or allow_url_fopen is on. The feed will now use the same locale setting that WordPress is using.

1.2

This upgrade provides support for localization. Feel free to use the ‘default.po’ file in the ‘languages’ directory to create a translation of the plugin.

What is the expiration date listed for the access token on the settings page for the plugin on your WordPress site? Could you let me know what you have entered in the Facebook ID text box? What do you have the limit set to on the widget or short code? Finally, when you look at your Facebook App at https://developers.facebook.com/apps, does it have a green dot next to the name?

Got a green light on the App. Expiration date is 16 September 2014. FacebookID is 171923356181106. Finally, when I set the limit to 1000, I get a warning from Facebook OAuth that the max limit is 250. Interestingly, when I set it to 250, I see all the FB posts!

When I set it to 1, nothing shows. When I set it to 2, 1 post shows.

Interesting. I bet FB updated something with array indexes on their side =)

I got the access token and everything looks right at the WordPress site – but blank. I entered 10152176214551636 as Facebook ID. And I have the green dot as well. So far so good – but still blank. I could send you a screen dump if it would help.

Hi, I can’t seem to get to the part where I get an access token and expiration because I get an error after I enter all my information in from facebook: “Given URL is not allowed by the Application configuration.: One or more of the given URLs is not allowed by the App’s settings. It must match the Website URL or Canvas URL, or the domain must be a subdomain of one of the App’s domains.”

Is there an updated version or something I need to get or something else I need to be doing? Thanks!

Hello! Thank you for your help and the plug-in.
I’m testing out on a hidden site updating WP to 3.9.1. I want to continue to use your plugin. It seems okay EXCEPT FOR I post quite a few FB posts with line-breaks, and most of there are showing up incorrectly as prose (line breaks missing). They show up correctly on WP 3.8.3. Is there an easy fix for this? You’ve fixed things easily in the past…. I can email you screenshots and links if you want. It seems to happen everywhere except Safari on laptop (but the linebreaks do get lost on mobile Safari).

P.S. – I just did a test of a NEW FB post with plenty of linebreaks, and that showed up correctly. So maybe(?) it’s just doing with these older posts and will be okay going forward? I don’t know.

Also, are you aware of any other issues I may need to watch out for with this plugin in updating WP from 3.8.3 to 3.9.1?
Thank you!

Update: I did more two tests to see if it is doing this with new posts also. The 2nd and 3rd test I did it ALSO removed the “returns” so it is NOT just happening with old posts as previously speculated. I do hope I can continue to use this plug-in.

Here is an example of what it’s doing: I post on FB:
“this
is
a poem
with returns”

and what shows up in the Wall Feed is:

“thisisa poemwith returns”

…So the returns are totally removed in-transit

I did contribute awhile back for this plugin and I do hope this missing returns can get remedied. Hopefully it is an easy fix….

UPDATE – APPEARS TO BE RESOLVED.
holy quakamango, i do not know what-all caused the other issues but now that i’ve actually done the update on my live site the Wall Feed seems to be working fine, as it was previously. it has the issue above on the hidden site but that does not matter since it’s hidden. it also had the issue in interim phases of updating the actual site but i just checked a bunch of places and now it is working fine. So As Of Now as far as i can tell there is No More Issue, and it appears to be working fine on WP 3.9.1.

Hi, thanks for creating this useful plugin!
I have a question about how to make the post content display shorter?
Currently, it shows all post content text in the feed, is anyway I can set the post content to display shorter?
For example, if a post content is about 500 words, how should I make it display only 100 words and end with a “…”?

I believe Facebook limits the number of posts that can be returned at a time to 500. You can try turning on the thoroughness option on the settings page for the plugin. This will force the plugin to continue making requests to Facebook until the limit your specify is reached. However, it will slow done the plugin dramatically.

Hi Takanudo
It seems something has changed… and all my posts return facebook content with the custom formatting intact, however pictures just show up as ‘Facebook Picture’, and no actual image is displayed

Thank you so much for providing this extremely useful plug-in. I have managed to install the facebook feed on a friends blog homepage and it seems to all be working fine apart from the links back to the original Facebook page. The ‘Like’ button does link back to facebook however if you click on comment or the profile name you receive the following message on facebook:

“Sorry, this Profile is currently unavailable.
Sorry, this profile is not available at the moment. Please try again shortly.”

There could be several reasons for this. The limit property tells Facebook how many posts to return. Some of those posts could be filtered out depending on how you have configured the plugin. For example, if you set the limit to one, the post returned may be filtered out if you have “Only show posts made by this Facebook ID” checked or “Show all status messages” unchecked or “Privacy” set to “Show only wall posts labeled public”. The thoroughness option forces the plugin to keep making requests to Facebook until the limit number has been reached, but it will slow down the plugin dramatically.

My token expired within the past week, and perhaps I haven’t been staying up to date but I performed the usual steps (log into WordPress, re-save the plugin settings connected to my Facebook account). But this time, the FB feed does not show. The error is gone, but the space is left blank. Please help, thank you!

I apologize. I left out a step from the previous instructions. Can you repeat them and then do the following:

1. Open ‘/wp-content/plugins/jsl3-facebook-wall-feed/php/class-uki-facebook-wall-feed.php’
2. Line 308 is the following:$fb_url .= "&fields=from.fields(id,name),privacy,message,name,caption,description,id,created_time,picture,source,link,likes.limit(1).summary(true),properties,icon,story,comments";
3. Replace it with the following:$fb_url .= "&fields=from.fields(id,name),privacy,message,name,caption,description,id,created_time,picture,source,link,likes.limit(1).summary(true),properties,icon,story,comments,object_id";
4. Save the file
